SHELL.

Application filed February 28, 1923.

To all whom it may concern.-

.Be it known that I, ISAAC C. SPENCER, a citizen of the United States, residing at Glendale, in the county of Kane and State of Utah, have invented new and useful Improvements in Shells, of which the following is a specification.

This invention relates to a shell for firearms, the general object of the invention being to provide means whereby a gun can be made to use ammunition of a smaller caliber than that for which the gun is designed.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the device.

Figure 2 is a longitudinal sectional View through one form of the invention.

Figure 3 is a similar view through another form.

Figure 4 is a cross sectional view through Figure 3.

Figure 5 is an end view of the device showing a modification.

Figure 6 is a longitudinal sectional view through such modification.

Figure 7 is a longitudinal sectional view showing a modificatlon.

Figure 8 is an elevation of part of this modified form.

Figure 9 is a section on line 9-9 of Figure 7.

Figure 10 is a sectional view showing a modification used with the shell which is to be loaded.

Figure 11 is a view showing the different parts of the ejector.

In these views 1 indicates a cartridgeshaped member which is formed to fit the cartridge chamber of a gun. This member is provided with a bore 2 and its rear end is closed by a screw threaded cap 3 so that the cap can be removed in order to place the shot and powder, as shown at 4, in the bore 2. The cap is formed with a chamber to receive a primer 5, which, when exploded Serial No. 621,914.

by the firing pin of the gun, will ignite the powder and thus propel the shot from the gun. Figures 3 and 4 show the device formed to receive a small cartridge 6 and in this case the cap 8 carries a plunger 7 which is provided with one or more projections 8 for engaging the cartridge to explode the same when the cartridge is struck by the firing pin of the gun. This plunger is slotted to receive a pin 9 which permits a certain amount of movement of the plunger.

In the modification shown in Figures 5 and 6 a spring 10 is located 011 the end of the cartridge-shaped member and is adapted to engage a small notch in the cap for holding said cap from rotary movement and thus lock the cap in place. In this form of the invention the plunger 7 is provided with a pair of projections 8 which pass through holes formed in the bottom of the cap. In other respects this form of the invention is similar to the form shown in Figures 3 and 4.

In the modifications shown on sheet 2 the cap 11 is provided with a threaded recess to receive a threaded projection 12 of the shell or body. The form shown in Figures 7, 8, 9 and 11 is designed to receive a shell as in the second form of the invention and in addition this device is provided with an ejector which consists of a member 13 which is pivoted in a recess in the cap by means of a pin 14 and is moved to eject the shell by the spring 15. The modification shown in Figure 10 is the same as that shown in the first form except the cap overlaps the reduced part of the shell, as shown at 16.

From the foregoing it will be seen that this device will permit a large caliber gun to be used with smaller caliber shells or with powder and shot and the device can be reloaded by removing the screw cap. The device can be easily and quickly removed from the gun so that the gun can be used for shooting cartridges for which it is designed.

In some cases it may be necessary to use a spring such as that shown at 17 in Figure 7 for holding the plunger 7 in its retracted position. This would prevent the firing pin or plunger from contacting with the loading shell which might cause a pre mature explosion of the shell. This spring must be stronger than the magazine spring of the gun.

I find that the primer may be used without powder as the gas generated by the explosion of the primer will drive a small shot from the gun so as to kill small birds: at short range. This will give better results than an ordinary air-rifle. When used with powder the attachment will give the same results as a 22-caliber cartridge. I may also use five or six small shots with powder and the primer for shooting rabbits and other game. This will take the place of a shot gun.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a cartridge shaped member adapted t engage the shell chamber of a gun. a cap having screw threaded engagement with the rear end of said member for permitting ammunition to be placed in the bore thereof, means carried by the cap for permitting the ammunition to be exploded by the firing pin of the gun and spring means for preventing rotary movement of the cap.

2. A device of the class described comprising a cartridge-shaped member, a cap having screw threaded engagement with the rear end of the member, means carried by the cap for exploding ammunition in the bore of the member, said cap having a recess which has a part extending through the inner wall of the cap, an ejector member pivoted in the recess and having an extension for engaging the rim of the cartridge placed in the member and a spring in the recess for actuating the ejector.

In testimony whereof I aflix my signature.

ISAAC CARLING SPENCER.
